GRAIP Analysis

Added: May 02, 2017 12:37 pm INTRODUCTION - The Shoshone National Forest has identified a need to complete a geomorphic roads analysis and inventory (GRAIP) in the Sunlight Basin area using the GRAIP road inventory process: https://www.fs.fed.us/GRAIP/manuals.shtml. At a minimum the Base Option (Section B) will be completed during the 2017 field season.

BACKGROUND & PROJECT AREA- The intent of this project is to develop an inventory that describe the road-stream sediment delivery and hydrologic connectivity; gully, landslide, and stream crossing failure locations and risk; and the condition of the existing road drainage network in the Sunlight Basin watersheds. The data will be utilized to inform future watershed improvement needs and projects. This project is also a "pilot" to determine if future forest-wide inventories would be beneficial and financially efficient.

The project area is generally located in the following area, Latitude: 44°40'43.48"N and Longitude: 109°39'8.98"W. It's approximately 55 miles northwest of Cody, WY. The road system contains seasonal closures from October 1 to July 15, steep high clearance roads best suited for ATV travel, and stream crossings. Grizzly bears are common, and food storage regulations apply to this area. Private land inholdings are also present in the area, and these areas are not part of the solicitation. The State land road segments are not currently part of this solicitation.

SCOPE - This solicitation includes application of Volume 1: Data Collection Method of GRAIP. The work includes data collection and GIS data cleaning (pre-processing).
